I usually define the other db connections in the database.php (as you have it above) then in the model you can call to it like:

$this->xxx_db = $this->load->database('xxx', true); 
$this->xxx_db->set($params);
$sql = $this->xxx_db->insert('table_name');

Doing it this way keeps all the connections in one place - its easier to maintain.

You may also want to see this question: Multiple database connections. I'm not exactly clear on what problem you are having.
